Postoperative Analgesic Efficacy of Erector Spinae Plane Block in Patients Undergoing Lumbar Spinal Surgery: A Systematic Review and Meta-Analysis.

Lumbar spine surgery is one of the most widespread types of surgery for treating back and leg pain. However, the postoperative period always presents with severe pain due to the removal of skin, subcutaneous tissues, bones, and ligaments. Patients usually require high doses of opioids to relieve pain during the initial three days after operation, as well as experience drug-related complications and prolonged length of stay in hospital. We found that Erector spinae plane block significantly reduced postoperative opioid consumption and pain scores. The present systematic review revealed that ESPB was effective and safe for postoperative analgesia.
